It's good that you are trying Rocky first.
Check the cables to make sure both channels are feeding the sound
card. Try injecting a signal about 2kHz off the center freq
(7.056MHz?) at a fairly large level from your signal generator. Look
for audio waveforms on both audio ouput channels.
It has been mentioned before, but make sure you are going into a line
input, not mic input to the sound card. Mic inputs are not stereo
(usually), and you get only one channel to Rocky.
If you are using a sound card that has an delay between I & Q, adjust
the I/Q sample delay, under view/settings/audio.
I'm sure more will come to me, but I must go do some stuff around the
